Philosophy is done by asking questions.

Could you go into more depth about what numerical identity actually is and its significance?
Ways the word ‘identity’ is sometimes used
‘The extent to which the colonists had developed a sense of an American identity was strong’
‘... in developing your professional identity. Develop the entrepreneurial mind-set ...’
‘I've struggled with this identity crisis’
‘Due to the increase in identity theft ...’
‘Things begin unpromisingly with a case of mistaken identity’

compression
(what are actually two things you take to be one)
e.g. the cars; indistinguisable twins
expansion
(what is actually one thing you take to be two)
e.g. Charly/Samantha, Clark/Superman

‘Identity is utterly simple and unproblematic.
Everything is identical to itself; nothing is ever identical to anything else except itself.
There is never any problem about what makes something identical to itself; nothing can ever fail to be.
And there is never any problem about what makes two things identical; two things never can be identical.’
Lewis, 1989 pp. 192--3

I have a question about the time aspect to both biological and psychological continuity. I don't understand what is meant when saying that a person exists at one time and then at another time.

If this were possible, could we not compare the two? Then confirm that there is a consistent identity?

Can you go into detail about someone with multiple personality disorder [dissociative identity disorder] and how (if at all) they’re psychologically/ philosophically an exception to the ‘having an identity’ vs numerical identity.
People with this condition believe they are numerous people despite having one physical body
and I am curious to know how this challenges the ‘having an identity’ vs numerical identity.
‘an identity disruption indicated by the presence of two or more distinct personality states (experienced as possession in some cultures), with discontinuity in sense of self and agency, and with variations in affect, behavior, consciousness, memory, perception, cognition, or sensory-motor functioning.’
Brand et al, 2016 p. 257
Appears to be correlated with trauma.
Found in roughly 1-1.5% of samples of nonclinical populations.

How is someone with dissociative identity disorder cared for?
‘In the first stage, clinicians focus on safety issues, symptom stabilization, and establishment of a therapeutic alliance.
‘In the second stage of treatment, following the ability to regulate affect and manage their symptoms, patients begin processing, grieving, and resolving trauma.
In the third and final stage of treatment, patients integrate dissociated self-states and become more socially engaged.’
Brand et al, 2016 p. 264
Treatment appears based on there being a single subject.

If we adopted a psychological continuity view, it would be coherent to supppose that multiple people could alternately occuply a single body.
But reflection on fission provides sufficient reason to reject psychological continuity views.
(Psychological continuity views are not view about personal identity.)
